Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pile press-in and pull-out machine, in particular a saddle having a plurality of clamps for gripping piles parallel to each other in the ground, substantially adjacent to a desired side of the parallel body of clamps. The present invention relates to a pile press-fitting and pulling machine that is mounted on the saddle and includes a chuck as a component that can be moved up and down relative to the clamp parallel body and that grips the press-fitted and pulled pile.

Technical background of the invention and its problems Pile press-in and pull-out machines having the above-mentioned configuration have been known in the art, for example, from Japanese Patent Publication No. 54-21644 and Japanese Patent Publication No. 54-21645, which were proposed earlier by the present inventor. When press-fitting piles into the ground or pulling out piles that have already been built, the pile press-fitting and pulling machine grasps the pile that has already been built with its clamp to make it stand on its own, grips the pile to be turned with a chuck, and uses hydraulic drive to By pushing down or pushing up the chuck against the clamp, it is possible to reliably apply a static load for pressing in or pulling out piles, and it is also possible to easily put down piles in water areas such as rivers and ports, and to construct anchors for pulling out. In addition, the chuck is of a type that is immediately applicable to the common parallel construction of sheet piles, that is, well-known channel piles, that is, lotus-komi turning in a zigzag arrangement in which the direction is sequentially varied by 180 degrees, that is, a type of pile. Use a chuck that can rotate around the vertical axis depending on the orientation, and make sure that the chuck can be moved not only up and down relative to the clamp, but also in the parallel direction of the lotus-filled pile and in the transverse direction. For example, the combination of the chuck's turning ability and its movability in the parallel and transverse directions makes it possible to perform so-called corner punching and pulling.

However, in this type of pile press-in and pile turning using a pile pulling machine, the pile that has sunk into the ground is grasped with a clamp as a reaction force anchor for pile press-fitting, so the head of the pile that has been placed in advance is at the point where the pile is being turned. It is necessary that the pile substantially protrudes from the ground or water surface, and for this purpose, it is necessary to lower the pile to a required height above the ground or water surface.

In this way, when pile construction work is carried out on roads, rivers, and ports that are accompanied by ships, the protruding head of the pile obstructs traffic, and to avoid this, it is necessary to A secondary press-down lathe is required to drive or press down the protruding head to the required height, but the method proposed earlier performs secondary press-in of the already press-fit pile while press-fitting the pile. Since it does not have the function of lowering the piles, it is necessary to wait until several piles have been folded in and then use the chuck for the secondary push-down turning of the piles, or use the pile press-fitting and pulling machine to lower the piles. The turning operation is not always simple, since the pile must be removed from the pile and the secondary pressing down of the pile must be carried out using a separate suitable turning machine.
In addition, in the previous proposal, it was not possible to move the pile press-fitting and pulling machine in the desired direction by itself for pile press-fitting and pulling-out lathe for corner piles. Furthermore, conventionally, a group of clamps that are installed on the machine base, which is a saddle, and grips existing parallel piles in the ground as reaction force anchors are divided into two halves, and the front and rear clamps can be driven relatively back and forth. A self-powered moving device that moves the pile by itself on the pile movement line by moving back and forth relative to the pile parallel pitch between the front and rear clamps, and by selecting the gripping and releasing of the clamps. A mast that can be rotated around an axis is installed on the machine base, and a chuck that can be rotated around a marking line for gripping the press-fitted and pulled pile is installed, and a chuck that can be rotated around the axis is provided between the mast and the mast. Pile press-in and pull-out machine with a movable elevating body mounted on the mast
No. 178047)] was proposed, in addition to self-movement on the pile arrival line as described above, relative vertical movement of the chuck with the clamp group, and movement between the front clamp and chuck combination and the rear seed. Combined with the relative back and forth drive of the pile parallel pitch in the pile parallel direction between the clamp and the appropriate selection of gripping and releasing of the front and rear clamps and chucks, the pile press-fitting and pulling machine can be operated. It is possible to self-step on the pile connection line, and therefore, this stepability, the horizontal turning ability of the elevating body and chuck combination near the mast, and the distance between the machine base, the mast, the elevating body combination, and the chuck. By combining the relative horizontal rotation drive, the pile press-in and pull-out machine can be turned in the desired direction by itself, even in so-called corner pile locations.

However, in order to perform the step mentioned above, the previously proposed machine requires not only the chuck but also the front clamp to be driven back and forth relative to the rear clamp, and the selection of grip release and pile re-grip to be switched. Because the configuration is
The above-mentioned change of direction at a corner pile pile inevitably requires an increased step operation due to the installation of the front clamp. In other words, in order to carry out the required self-powered movement (excluding direction change operations in the horizontal plane), the following steps are required: 1) With the chuck open, special raising, 2) With the front clamp open, the clasp and chuck combination move forward, ■ Re-grabbing the pile with the front clamp in the forward position, ■ With the rear clamp released,
Pulling to the front clamp side, ■ Grasping the chuck against the corner dumping reaction pile or a new regular pile, ■ Lifting the front and rear chuck combination while supported by the mounting chuck, and ■ Lowering both clamps. At least seven operations are required, such as re-grabbing the pile, and changing direction is not always simple. In addition, in the previously proposed machine, each of the front clamp and the rear clamp is equipped with a pressing plate that can be driven downward, and the pressing plate presses the upper end of the pile. It has a structure that does not have the maneuverability of a very small degree of depression compared to the length, and can contribute to the simultaneous turning of the pre-indicated secondary depression of the already press-fit pile in conjunction with the pile press-in by the chuck. do not have. Purpose of the Invention Therefore, the present invention is capable of simultaneously carrying out lotus-in turning of piles and secondary push-down turning of piles that have already been built, and is also capable of performing pile press-in and pull-out turning at corners of piles. The aim is to ensure that the driver can easily make a self-directed change of direction in the desired direction.

Structure of the Invention The pile press-in and pull-out machine of the present invention includes a saddle equipped with a plurality of clamps for gripping piles built in parallel on the ground, and mounted substantially on the saddle adjacent to a desired side of the parallel body of clamps. In a pile press-fitting and pulling machine, the pile press-fitting and pulling machine includes a chuck that can be moved up and down relative to the clamp parallel body and grips the press-fitted and pulled pile as a component, and the pile press-fitting and pulling machine is equipped with a moving machine. , the mobile device is
A saddle equipped with a clamp that is placed adjacent to the opposite side of the chuck of the above-mentioned parallel clamp body and grips the parallel pile already built in the ground, supporting the saddle and preventing relative vertical movement between the saddle and the saddle. A deck capable of quickly responding to the secondary pressing down to the required height of the pile, and installed on the deck and having a distance greater than the pitch of the pile to be lowered between the deck and the same deck,
It is characterized in that it is capable of relative back-and-forth driving in the pile paralleling direction and includes a beam connected to the saddle of the pile press-in/pulling machine as a component.

Function of the Invention In the present invention, a pile press-fitting/pulling machine grasps existing piles arranged in parallel with its clamps and makes them self-supporting, and by pushing down (or pushing up) the chuck, it can press a certain pile in the same manner as in the past. When the press-fitting (or pulling-out) is completed, the clamp on the mobile machine grips the pile that has already been built, or the clamp is initially gripped on the pile that has already been built), and the clamp and chuck of the pile press-fitting and pulling machine are released. The deck of the moving machine is raised together with the pile press-fitting and pulling machine so that the release clamp and chuck are located above the pile, and the pile press-fitting and pulling machine is moved by the parallel pitch of the pile, as required for the beam of the moving machine with respect to the deck. Move it by driving it to the side, lower the pile press-fitting and pulling machine at the moved position, grip the existing pile again with its clamp, and release the clamp of the moving machine.
Raise this together with the deck above the pile, and move the deck and clamp to the required side by the parallel pitch of the pile.
By moving the pile press-fitting and pulling machine, lowering it, and grasping the pile that has already been built with the clamp again, or by performing the above series of operations in reverse, the pile press-fitting and pulling machine is placed parallel to the ground and the pile is pulled out. 1 on the lotus row line of the pile
The pitch can be stepped to the required side for pressing in and pulling out a new pile, and in parallel pile turning, the pile can be pressed in and pulled out on an existing pile with the pile press-fitting and pulling machine in a free-standing state. A secondary depression of the folding pile to the required height can be achieved by pushing down the clamp of the moving machine together with the deck relative to the pulling machine. Effects of the Invention According to the present invention, the moving machine combined with the pile press-in and pull-out machine not only contributes to the steps of the pile press-in and pull-out machine in the pile parallel direction, but also contributes to the movement of the pile. The clamp of the machine also contributes to the secondary pressing down of the pile to the required height in parallel pile turning, so the secondary pressing down can be easily carried out, and the secondary pressing down of the piles that have already been press-fitted can be carried out easily. This can be done by simultaneously press-fitting the pile to be press-fitted and rolling it out at the same time.

In addition, since the present invention has the above-mentioned step function, when the chuck is of a conventional type, that is, one for general parallel setting turning of groove-shaped piles, its rotatability and the ability to move across the parallel direction of the lotus pile pile. A combination of movement in the direction, a step function, that is, a deck in the moving machine, in other words, a clamp and pile press-in, a combination of a predetermined degree of relative vertical drive and back-and-forth drive between the pullers, and a moving machine clamp. And by appropriately selecting and switching between pile press-in, pull-out machine clamp, chuck grip, and release, it is possible to perform pile press-fit and pull-out work at corner pile piles without the chuck or clamp getting caught on the pile at that location. It is possible to change the direction of the pile press-in and pull-out machine by itself in a desired direction, and this can be done simply.

That is, in the present invention, the pile press-fitting at the corner pile location and the automatic movement of the pulling machine to change the direction (however, excluding the direction change operation in the horizontal plane) are: In the open position, special raising, ■ Pile press-in and pull-out, forward movement of the rock, ■ Corner dumping reaction force in the forward position, gripping the chuck against the pile or regular pile, ■
Under the support of the chuck, under the release of the moving machine clamp, lifting, ■pile press-fitting, pulling the moving machine clamp to the pulling machine side, and ■moving machine clamp, pile press-fitting, and lowering the pulling machine clamp to re-grasp the pile. This is achieved through six basic operations, and the operation is simpler than the previous proposed machine.
